'TYPE-WRITING MACHINE.

Specicaton of Letters Patent. Patented Aug. 31, 1915. p

l Application filed January 7, 1914. Serial N0. 810,712.

T0 all lwhom t may concern Be it known-that I, FRANK C. URSBRUCK, acitizen of the United States, residing in New York city, in. the countyof New York and State of New York, have invented-certain new and usefulImprovements in Typel-Vritilg Hachines, of which the following is aspecification.

This invention relates to typewriting .inachines, and particularly tomeans for enabling-the use of a plurality of sets of typee bars in whichthe types or characters of one set are of a diierent width' or size fromthose of the other-'set and require letterspaces on the work-sheet ofgreater width for the characters ot' one set than for those ot' theother set.

This invention relates principally to machines of the kind disclosed inan application of Stephen T. Smith, Serial Number 802,337, filedNovember 22, 1913, in which a paper carriage may be translatable fromone set of types to. another set, each set having its own keys. The typesets may be placed side by side, and the carriage may run upon amultiple-length track which enables it to coperate with either set oftypes at the will of the operator. Thus the number of types for use witha single paper carriage niav be doubled, and in order to permit the useof larger types with one set, or

characters requiring wider space on the work-sheet than required by thecharacters of the other set,Y the invention provides means whereby thepaper carriage, when cooperating with one set oi types, is lied throughletter-space distances of greater eX- tent than when cooperating withthe Aother set. Thus larger types may be used ywith yone set than withthe other, or the wider type blocks may be devoted to italics or script,or. the two keyboards could be deetc., or various other combinations'nay be used. A

This invention also gives the operator the choice of writing letters,bills or other' typewriters, two separate machines Wouldbe required.Also different styles of t pe might obviously be employed on the dierent sets of type-bars.

The present invention is also of value in adapting one machine forwriting a number of different .languages where the characters of onelanguage require a wider space than the characters of another language.Thus, for example, the larger types might be used for writing a languagesuch as the Korean language in which a numberof characters are groupedtogether and printed by a single type-stroke, such a group requiring awider space than the individual characters of another language, such asEnglish, which could comprise the smaller types.

In the preferred manner of carrying out the invention, there may beemployed tWo Underwood front strike machines, which may be placed sidevby side and iXed together, therusual carriage tracks being replaced bymultiple-length front and rear rails. anda single carriage may be run onof two keyboards, as more than two key- 'boards and two sets of typesmight obvioushY be employed.

The carriage track may be` of sufficient length to permit the carriageto be shifted along the rails into'coperative relation with the desiredset of types, each set of types being provided with its own keyboard.VThe letter-space feed of the carriage, when cooperating with any set oftype keys, is coni trol-led by an'escapement rack on the carriagerunning in mesh with an escapement pinion mounted upon the machineframe. In accordance with the present invention, and .to permit the feedto-be varied for the different sets of type, a plurality of' feed racksare provided upon the carriage, a

' respectively.

y riage rail 5 separate rack and letter feed mechanism belng employedfor each setof types, said mechanisms being so proportioned that theletter spacings correspond with the size of type employed inthecorresponding set.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective plan view ot'one form of machine made in accordance with thel present invention.Figs. 2 and 3 are detail views of the escapement mechanism at thelefthandand right-hand sides of the machine, Fig. 4 is a rearperspective view of the mechanism shown in Fig. 2, the escapement wheelbeing omitted. Fig. 5 is a sectional elevation tak'enabout centrally ofthe right-hand main portion ofthe machine, as shown in Fig. 1. Figs. 6and 7 are views of types ot' diti'erent-sizes for use at the left-handand right-hand sides ofthe machine, respectively.

In practising the invention in the form illustrated, the frameworks 1and 2 of two Underwood front-strike typewriting machines may be rigidlysecured by fasteners 3 5) upon a common base Jr, and they may also berigidly joined by a rear carand a front carriage rail G, each of whichrails extends from the left-hand end ofthe frame 1 to the-right-hand endof the frame 2. Upon these rails may travel a carriage 7, which, asshown, is an Underwood typewriter carriage of the usual con- Structon.`This carriage 'has front rolls 8 which run in the groove of the rail ortrack 6, and collars '9 which rail 5 I The carriage is preferablyprovided with a-plurality of feed racks, one for each set of type-bars12 and 13; these racks 10 and 11 being adapted to be brought into meshwith pinions 14 and 15 mounted upon the 'rightdiandand left-hand frames2 and' 1,

respectively. The feed racks 10 and 11 may be connected together andform part of a swinging frame 16 pivoted on the carriage 7 and operableby a key"17 to lift theracks 4and thus release either rack "from itspinion.

The pinion 14 may be connected in the usual 'manner through a one-waydriving pawl 18 toan escapement wheel 2O controlled by a dog rocker 21,the latter actuated by type keys 22 mounted on levers 23 connectedthrough sub-levers 24 to typefbars12, which have heels,"25 to thrustbackwardly a uni# versal bar 26 mounted on links 27 and adapted tostrikethe dog rocker 21. The type keys 28 connected tothe type-bars 13 operate4in like manner through auniversal bar and a'dog rocker 21a to controlan escapementr wheel 29.

Assuming the carriage 7 vis in the righthand Writing'field, as' shown inFig. l, the

operator l-nianipulates thel keys 22 to swing` engage the rear guidetherewith, the rack the type-bars 12 upwardly 'and 'rearwardly to bringthe types El() thereon against the front face cf the `platen 31,. andthe carriage is fed along, step-bv-step in the usual manner, the rack 1Uheilig in mesh with the pinion l1 and perniitting the carriage t0 moveforwardly at each type stroke a distance detcrn'iined by the pitch ofthe teeth on cscalnmeut wheel 2i), andthe diameter of the pinion 1i,such distance ably the distance between adjacent teeth of the rack 10.Ribbons ffl-2 mounted on' spools 33 operate in the usual manner.

An index pointer 34 on the carriage moves over a scale 5&5 on the frontrail (i: the gradua'tious on the spond with the the carriage wheel 20.

lt' at any time, the operator wishesto use the set of types 36 in theleft-hand system, he depresses the release'key 17 to vlift the rack l0free from thev pinion 14, and then shift-s the carriage to the left tobring the work-sheet ,to the writing position fol,` `the types fltj Thekey'l7 is then released and permits the rack l1 to drop into mesh withthe pin-ion 17 (Fig. lVriting may then' proceed in the usual manner. thekeys 2S being n'ianipulated to actuate the types 36.

lly comparing Figs. 2 and 3,it will be observed that the rack l0 canonly mesh with the pinion 14, and also that the rack 11 can only bebrought into mesh with the pinion 15. TheV rack l() being somewhat lowerthan the rack 11, holds the latter away from the 'pinion 14, and thepinion 15 being located forward of the rack 10 and out of alinement 1lis permitted to move downwardto engage the' pinion 15.

letter-space movenieuts of being prefer-v scale being spaced to corre ascontrolled by the eseapement A As indicated on the drawings,the diameterofthe pinionv 15 meshing with therack 11, is greater than that of thepinion 14 on which runs the rack 10, thus providing for feed of thecarriage through comparatively wide letter-space.distances when in -thezone of the types 3G. The same result might be obtained in other ways,as forA example,.by having the teeth on ,the two escapernent wheels 20and 29 'of different pitch.l These letter-spaees may, for example, be inthe ratio of 8 1:0.10, as indicated by the scales 35 and 37, thegraduationsof which are spaced to correspond with the letter feedmovements of the carriagewhen controlled throughthe racks 10 and 11,respectively.

, Obviously the ratio, as well as the'absolute value of the letter-spacedistances might be varied, or the positions' of escapement mech- Aanismsinterchanged.

with upper and lower case types either of which may be called into useby a shift key 40, and the type-bars 12, as indicated in Fig. 7, arealso provided with upper and lower'case types either of which may becalled into use by the operation of a shift key 41. Thus on a singlepiece of work all of the different types may be employed.

AThe shiftkeys 40 and 41 are for temporar-y use, each being helddepressed 'while the type keys are manipulated. The keyboards are alsoprovided with permanent or locking shift keys 42 and 43. which lock theplaten 3l in the upper shift position. The shift keys are connected tothe shift rail 44 through suitable mechanism comprising a shift frame45, whereby when a shift key is depressed, the rail 44is lifted andthrough l a shift roli 460m the' platen frame lifts lthe platen frameand platen to the upper shift position.

At the right-hand end of the frame` 2 the usual adjustable margin gage47 for limiting the return stroke of the carriage in determining thebeginning of a new line. The usual left-hand margin gage is omitted fromthe frame 2 in order to permit the shifting of the carriage across tothe frame 1, and the usual right-hand margin gage is omitted from theframe 1 for the same reason. Fig. l, however, carries the usualadjustable let-hand'margin gage 48. Each keyboard is also provided witha space key, said keys shown at 49 and 50, and in general each sectionof the machine'` cooperating with the carriage forms a completetypewriter of itself.

Varia-tions may be resorted to within the scope of the invention, andportions of the improvements may be used without others. Having thusdescribed my invention, I
